Industry Concerns Relating to Natural Roof-Lighting Being Classified As Brittle and Therefore

Introduction

Industry concerns relating to Natural Roof-Lighting being classified as “brittle” and therefore possibly posing

a danger to foot traffic on a roof, has led to Alsynite NZ purpose developing a heavy duty and high impact roof

lighting system to alleviate these concerns. Aptly named Topglass Ultra-Safe, the product utilises a heavy duty,

woven roving reinforcing system positioned within the resin matrix, thereby providing exceptional strength. Further, the innovative fastening system jointly developed by Alsynite NZ Ltd and the Company's fastening supplier

provides maximum security to any foot traffic across the roof whether this is day, night or in times of restricted visibility.

Key Benefits

• Topglass Ultra-Safe is manufactured utilising heavy duty woven roving enclosed within the resin matrix which

in turn provides a structural capability not normally available with traditional

translucent roofing materials.

• Topglass Ultra-Safe meets the impact strength tests of AS/NZS 4040 and AS/NZS 1562 alleviating the need for

safety mesh to be installed under the sheeting (* see safety) This is of particular benefit to building designers

who face corrosive atmospheres damaging the safety mesh zinc coating

• As the roving matrix runs both

longitudinally and laterally within the sheet, Topglass Ultra-Safe demonstrates

exceptional high impact strength

• A 100 micron Silmar Gel coated surface provides long term light transmission and is supported by a 20 year weather surface structure warranty

• Corrosion resistant when installed in wide range of aggressive environments

• Excellent spanning capabilities

• Topglass Ultra-Safe is marketed as a safe roof lighting system, rather than

just a roof lighting product

Applications

• Educational facilities and Public

Assembly areas where there is a

danger of persons climbing onto a

roof exists

• Fertiliser Plants

• Chemical and Powder-coating Plants

• Wool scouring facilities

• Waste water treatment plants

• Salt Extraction Facilities

• Severe marine environments

• Natural roof lighting where safety

mesh is not installed

• Wood Pulp and Paper Plants

Special Applications

• In very severe corrosive environments the Topglass Ultra –Safe resin system can be fortified using Vinyl Ester to provide maximum protection

• Topglass Ultra-Safe can be supplied

as heavy duty a solid coloured

roofing and cladding material to

replace metal roofing products for

use in corrosive environments.
